Referring in detail to the drawings and particularly to Figures 1-6,inclusive, 6!) denotes generally a complete full automatic machineconstructed to embody the invention and comprising in combinationcooperating apparatus. devices and mechanisms for making complete teaballs M of the pillow type with stapled string handles S and tags T orthe like articles on large scale production.

As seen from Figures 1, 16 and 17, said machine 60 comprises a teasupply feed measuring mechanism A which provides successive charges ofpredetermined quantities of tea to bags Ml made by an apparatus B whichreceives cloth for making said bags Ml of cut unit sections M2 from atubular cloth strip M3 of a suitable supply C.

The bags Ml, after being filled with tea by a hopper 64 as shown inFigs. 19, 20, 21, and 23 are transferred to apparatus D for sewing thetop closure seam 0. See Figs. 25, 26, 27 and 28. The closed bags M4 arenext operated upon by a string handle and tag applying device E toanchor one end of each string handle S to bag M6 at the top closure seamO, the finished bags M finally being transferred to discharge apparatusF with the string handles S and tags T in nontangling position ready forpacking in shipping containers.

All the parts of machine 6! namely, the measuring feed mechanism A, bagmaking apparatus B, bag clothv supply C, top closure apparatus D,

string handle and tag applying device E, and discharge apparatus F, areinterconnected in coopcrating timed relation by suitable driving andpower transmission means G. This driving and power transmission means Gis controlled through the operation of a hand shift lever 65, theinterconnecting portions of which by a suitable clutch control 65d canselectivelyoperate the machine in conjunction with the string handleattaching device E or with the latter shut ofi, as will hereinafter bedescribed.

The tea supply feed measuring mechanism The mechanism A may beconstructed of parts assembled to operate in the manner similar to thatdisclosed in Letters Patent No. 2,015,071, granted September 24, 1935 toLouis Hirschorn and Hans Irmscher and is seen to comprise a tea storagereceptacle 6| in which the bulk of the tea supply is stored. Saidreceptacle 6| has extending diagonally therein a stirrer 6la which isintermittently driven through a ratchet drive Bib. The latter isactuated by a crank and lever drive Me which in turn is operated from acam mechanism 61d. A bell crank and. linkage file is also driven by saidcam mechanism Bld for operating the ratchet tooth roller drive Hi tofeed the tea from said receptacle 6| to a conveyor Blg which emptiesinto an auxiliary feed receptacle 62a having an agitating means 62. Thestirrer 6la., ratchet tooth roller drive 61) and the conveyor Big serveto break up any mass or lumps of tea so that the latter is fed to saidreceptacle 62a in a loose, freely flowing stream. Said conveyor Hg isdriven through a ratchet wheel drive Blh which interconnects with thebell crank and linkage (He.

The auxiliary receptacle 62a is provided with converging bottom walls,one of said walls being formed by a slidable bar 62b which rests uponthe backing plate 62c, the other of said walls by a swinging bar 62dsecured to a lever 6242. The swinging bar 62d moves in the path of flowof the tea and when swung upwardly into the auxiliary receptacle 62akeeps the tea from escaping therefrom. said bar 62d being provided forthis purpose with an arcuate shaped extension gate 62f which moves inposition to shut off said flow. The bar 6201 is swung back and forth inunison with the movement of the linkage Ble, and the bar 621) isactuated through the linkage 62k and cam 627' for slidable movement backand forth upon the supporting plate 620.

The receptacle 62a empties into a flexible conduit 62 which is vibratedby a shimmying motion to prevent the tea from clogging therein, andserves as positive feeding means to the restricted inlet of a rotarymeasuring device 63. The shimmying motion of said conduit 62g isprovided through a cam transmission 62h, driven by a verticallyextending drive shaft 66 which also drives the cam 627' and the cam Bldof the receptacle stirrer Ma.

The lower end of said, drive shaft 66 is formed with the crankportionifl which through a reciprocating rack 68 rotates the measuringdevice 63 so that a predetermined amount of tea is taken from theflexible conduit 62g and delivered to a feed hopper 64, all in themanner described in detail in the aforementioned patent application.

The drive shaft 66 below the crank portion 61 carries a drive cam I65for operating a shear 19 (see Figs. 28 to 33, inclusive) to sever theinterconnecting thread stitches formed between successive bags M4 afterthe top closures have been applied by a sewing machine I53 in the mannerhereinafter described.

Said drive shaft 66 below said cam. IE is terminated by a bevelled geardrive H which connects with a jack shaft '12, the latter being driventhrough a pair of helical gears 13 by a main power shaft 14. Said mainpower shaft 14 may be driven by a motor or other suitable power source(not shown) through a belt 65a and said clutch control 65d, as shown inFig. 5.

It is also desirable to provide between the cam I65 and the bevel geardrive H a clutch 208 having an operating handle 209 (see Figure 1) whichserve to selectively cut off the operation of the tea supply feedmeasuring mechanism A. Said clutch 288 may be of any well knownconstruction and preferably being of the friction or spring pressedcontacting surface type which is adapted to yield should anyobstructions such as a nail pass to the measuring device 63. Byoperating said handle 289, the entire mechanism A driven by saidvertical drive shaft 66 and the crank portion 61 is made inoperative.The remaining apparatus, devices and mechanisms forming machine 69 maybe operated and are controlled through the lever 55 as described above.

The vertical drive shaft 65 has a semi-circular housing 66a whichextends therearound and is bolted to the top of frame H of machine 60.This housing 86a, serves as guard to shield the said shaft 65 and themoving parts driven thereby, and also supports a top bearing 66 of saidshaft.

Bag cloth supply and. feeding mechanism Referring now to Figures 1, 2and 5, the cloth supply C may be enclosed in a container 80, the tubularcloth strip M3 preferably being fiat rolled and is unwound by passingout through a slot Sim provided in the container 80 and around asuitable projecting guiding pin 82 which extends from the frame H of themachine 50. Said strip M3 is then fed to the bag making apparatus B bymeans of a reciprocating cloth feeding mechanism 83.

As seen from Figures 1. 2, 5 and 6, the cloth feeding mechanism 83comprises reciprocating gripp ng means formed by a jaw 83a and a bar 83bcooperating therewith which clamp the strip M3 during its lowest orretracted position and on moving up draws up the strip M3 from thecontainer 89, unwinding same to feed an amount to the bag mak ngapparatus B sufficient to make bag. The jaw 83a. and bar 83b of saidgripping means are carried on the free end 83d of acam lever $30, theinner end 83c of said lever 83c cooperating with a cam 53f which is seento turn with a main cam shaft 84. Said cam lever 83c is fulcrumed onbolt 83g supported on a bracket 83h which extends from the frame H.

The fulcrum bolt 83g is adjustable along a slot 837 in the cam lever 830as shown in Fig. 6b so that the movement of the lever can be varied forsupplying a desired length of the strip M3. By this simple adjustmentand another of equal simplicity hereinafter described, the size of thebag made by the machine Gil may be varied, this variation resulting inshortening or lengthening the depth of the bag.

Now referring to Figures 6, 16, 17 and 18, it is seen that there ispivotally attached to move with the lower end of cam lever 830 avertically extending connecting rod 83k, the upper end 83m of which ispivotally connected to a vertically slidable frame member 8311. Saidmember 8311 is guided in its movement by a vertically extending rod 830which is engaged by the side bearing block 83p extending from said frame8311. The free end 83d of lever 830 carries a vertically extending bar831, the upper end of which slides in a bracket 83s having a suitablescrew adjustable friction tension means 8315 to control thereciprocating movement ofthe mechanism 83 in order that the same mayoperate smoothly.

The frame 831% has mounted thereon a pair of clamping feed rollers 8311.which cooperate with the jaw 83a and bar 83b of the cloth feeding rmechanism 83 to feed the bag strip M3 from the container to the bagmaking apparatus B. Said rollers 8314 are journalled on clutch shafts8311 which permit each of the rollers 83a to rotate only in onedirection, the rotation taking place on the downward movement of theframe 831:. Each shaft 831], as shown in Figure 18, comprises a pivotedspring pressed clutch pawl 83w which engages the counterbored annularsurface 832 of the feed rollers 83a for eliminating any possible freeturning movement of said rollers 8311,. A friction belt 833: is threadedto extend between said rollers 83a for eliminating any possible freeturning movement of said rollers 83a. Said belt 83a. may be anchored atone end at a bracket 83y extending from the frame 8311, the other endthereof is provided with a tension spring 832 which may be secured tothe machine frame H.

Suitable interconnecting guides 831 mounted above and below the rollers83a may be provided for retaining the cloth strip M3 in proper alignmentwith relation to said rollers 83a.

Extending through the leading end of the tubular strip M3 and engagingbetween the rollers 83a there is a tongue member 85 having an enlargedupper portion 85a which may be cutaway along its opposite edges at 851)so as to be slightly narrower than the width of said bag strip M3. Theportion 85a. of said tongue member 85 is gradually tapered downwardly inthickness for a short length to provide a relatively thin flexibleportion 850 in the remainder length thereof to extend a distance belowthe rollers 83u, as shown at 85d in Figures 16 and 1'7, the enlargedportion of the tongue 85a being limited in its downward movement withrespect to the tubular bag material M3 by a pair of spaced rods 85c.

The portion 850 of tongue member 85 passing within said strip materialM3 and between the rollers 83a is formedwith an S-shaped bend to retainthe tongue member 85 within said material M3 to permit movement of saidmaterial with respect thereto in the following manner. The upwardmovement of the slidable frame 831i takes place while the jaw 83a andthe bar 83b grip the strip material M3 together with the tongue por--tion 850 therein. Just prior to the upward movement of said frame 81in,shear blades 86 complete the severing of the upper portion or bagsection M2 from the strip material M3 which is to form a single tea bag.The shear blades 85 thereafter open up to permit the passagetherethrough of said strip material M3 gripped and carried by the frame831i carrying within said material M3 the tongue 85, said material M3then moving from a lower position below the shear blades 86 to the fullyraised position above said blades 86 as shown in Figures 16 and 17.

The strip material M3 at this extreme raised position will be engagedand held by suitable means forming part of the bag making apparatus Bhereinafter described and the frame 8311. will thereafter start in itsdownward movement. During this downward movement, the rollers 83a arereleased for rotation and ride along the outside of the strip materialM3 which is held by its upper end against return movement. Due to theS-shaped form of the tongue member 35 retained between the rollers 83a,said tongue member 85 will be retracted within the material M3 and willmove in unison with said rollers 8311. until the enlarged end 85a againtakes the position below the shear blades 86, as shown in Figure 1'7. Atthis time the frame 831: has arrived at its lowermost position and thestrip material M3 above the enlarged tongue 85 is then again free topermit the severing thereof by the shears S5 to form the bag section M2.

As said bag material M3 before being out is projected up beyond the endof the enlarged upper portion 850. of the tongue member 85 and the 1shear blades 86, said enlarged tongue portion 85a spreads open the upperend of the bag material M3 sufficiently to permit the same to be drawnover spaced fingers 90 which are in parallel alignment with the widesides thereof extending in the same plane, as shown in Figures 16 and1'7. These fingers 99 are rotatably mounted about spaced axes passingthrough the length thereof by means of shaft portions 990. which arejournalled in cooperating toothed segment member 9I. Said segmentmembers 9| are pivotally mounted on stud shafts 92 which are spaced andextend in parallel relation to a radial axis X-X of a horizontallydisposed turntable frame 93 see Figures 5, 16, 17 and 21).

As seen from Figures 16, 17 and 22 the segment members 9| carryupstanding posts 9 I a. which are interconnected by a tension coilspring 9 I b. This tends to keep the fingers 90 in extended spreadposition, namely, in substantially parallel alignment and is sufficientto put a slight strain on the material of the bag when engaged thereon.The turning of segment members 9! for moving the fingers 99 to and fromeach other is accomplished by means of a movable arm I29 which is pinnedat the end of a vertically extending rod I2I. The-lower end of said rodI2I is extended and is pivotally secured to a cam lever I22 which has acam roller I22a cooperating with a cam I221), the latter being securedto a cam shaft 84, the lever I22 being fulcrumed on the jack shaft I I3(see Figures 5, 6 and 16).

The movable arm I2 0 is operated through said cam I221) and saidinterconnecting lever I22 and rod I Z-I for projecting it in the path ofmovement of an extending portion 9Ic integrally formed with the segment9 I. The arm I serves to press said portion 9Ic for swinging thesegments 9! which are interlocked through teeth 9Id against the actionof the spring 9Ib to bring the fingers 99 together so that they willreadily enter the open upper end of the cloth M3. This action takesplace at a hereinafter called first station where the bag strip materialM3 is fed to the turntable assembly forming the bag making apparatus B.I

The turntable frame 63 is in the form of a spider having a hub 93a whichis secured to rotate with a vertical shaft 94, the latter bein journaledin the spaced upper and lower ball bearings 95. The lower ball bearing95 is supported by a cross tie plate 96 and the upper bearing 95 on anangle bracket 91. which are carried by the machine frame H. Adjacent tothe upper bearing 95 carried by the angle bracket 91 and vers 99c.

below the frame 93, there is provided a gear wheel 98 secured to turnwith said hub 93a. Said gear wheel 98 meshes with a pinion 99 supportedon a bracket IIJila extending from an upper horizontally extending armIiiilb which turns on shaft 94 and also has bolted thereto an uprightsupport frame I00, as shown in Figures 5 and 20. Said arm I601} and asimilar lower horizontally extending arm I630 spaced therefrom supportsaid frame I09 for free turning movement on the shaft 94, said armsIilflb and I680 being assembled to fit between the cross tie plate 96and angle bracket .91, as shown in Figure 5.

Referring now to Figures 2 and 20, the pinion 99 is seen to be driven bymeans of a flexible shaft drive IBI. The lower or drive end of saidshaft IIiI comprises sprocket wheel I02 which is connected through alinkchain I as with an intermediate idler sprocket IM, the latter beingmounted to turn on shaft I65. Said chain I03 is driven through asprocket I03 mounted to turn with the vertically extending shaft 65 (seeFigure 2), the latter being driven through the bevelled gears II asshown in Figure 5.

The spaced fingers 96 carried by the spider frame 93 are adapted torotate vertically through an arc of degrees so that said fingers So canswing from a position of alignment of the flat sides in the same planeas shown in Figures 16 and 17 to an alignment with the fiat sides inparallel planes as shown in Figures 19 and 20 for opening the bag MI toreceive a charge of tea. To accomplish this rotary movement, short crankarms 93b are provided and disposed at different levels, said arms beingpivoted to turn with the shafts 99a, as shown in Figure 16, one of thecrank arms 98b of each pair of fingers 90 (the one on the right) beinglocated just below the level of stud shaft 92, and the other (on theleft) is located above stud shaft 92. As seen in Figure 21, these crankarms 99b are connected to opposite ends of a forked member 990, the bentmid dle portion of said member 960 engaging around pivoting pins 9Mwhich extend up from cam le- The latter are pivoted at 9B uniformly onthe rim portion of the spider frame 93 to permit swinging the free endsthereof which carry rollers 999 to ride in a cam groove Ifii'a of arelatively stationary cam member I01. Said cam member I9? is supportedon the hub portion 93a of the spider frame 93 but is retained againstrotation by the upper end 97a of the angle bracket 97 secured to thecross plate which in turn is supported on bed frame H (see Figures 5 and12).

The upright support frame I Bil carries gibb mounting I03 for adjustablycarrying a sewing machine I719. Said frame Iiiil with the gibb mountingI63 oscillating to permit the advancement of the needle Iiidd of sewingmachine I 39 while applying a stitch seam closure Q at the bottom of thecloth bag section M2 in the manner hereinafter described. Said machine I09 is driven through a pulley Him, a belt I691) which runs over twoangularly disposed idlers H0, and a drive pulley Iago, the latter beingmounted to turn'with the main drive shaft is, all as shown in Figures 2,5, 6 and 12.

The oscillating of the support frame I 99 together with the sewingmachine Hi9 about the shaft 94 carries the pinion 99 permitting thesewing machine I89 to accompany the bag sections M2 during the seamsewing operation. As seen in Figure 12, said oscillation is accomplishedby providing a connecting bar III which has one end pivoted Ilia to thesewing machine I99 and
